ISAACl CHAPMAN, OF HORSEHEADS, NEW YORK.

' MILK-CAN.

sPEcIirrcATIoN forming part of Letters Patent No. 264,403, datedseptember 12, lesa.

To all whom it may. concern:

Beit known that I, ISAAC CHAPMAN, a citizen of the'United States, and aresident of Horseheads, in the county ot' Chemung and State of New York,haveinvented certain new and usefulImprovementsiMilk-Cans;andIdoherebydeJ clare that thefollowing is afull,clear, and exact description of theinvention,which will enable othersskilled in theart to which it pertains to make and use the same,reference beinghad to the accompanying drawings, and to the letters ofreference marked thereon, which form a part ot' this specication.

My invention consists in certain novel combinations ot' devices forstrengthening the bottom ot' milk-cans, which will be hereinafterdescribed, and pointed out in the specication and claim.

In the drawings, Figure 1 is a side elevation. .v Fig. 2 is a sectionalelevation. Fig. 3 is a plan view of the bottom of the interior cylinder.Fig. 4, is a side elevation ot' the cover, and Fig. 5 is a detail view.

The milk-can A is provided with au inner and outer vertical cylinder,the outer wall or cylinder, E, being formed into a supportingbase andcorrugated from a short distance above thebottomd of' the can to itslowest terminal "point, and it is also corrugated to form thestrengthening-bands d d at'the upper part ot' the can.

F/represents the inner can-cylinder, having the bottom d', which isadditionally supported and strengthened by the cross-bars h It, Fig. 3.This bottom is composed of the metallic diskf, having the circular andvertically-projecting iiange f rigidly secured thereto, the cross-bars hIt being soldered to it where they intersect, and at their ends both tothe diskf and to the outer cylinder, E, on the inner side ot' the same,near the base, and crossing each other at right angles underneath thebottomd. The inner can-cylinder, F, is soldered at S S to the outercylinder, E, Where cylinder E pro- Application led February 18, 188:2.(No model.)

jects, slightly curved, over the top of that cylinder.

A represents an annular shoulder formed at the lower part ofthe neck ofthe can, in order to furnish a lodgmentfor the rubber or other elasticpacking, a, placed thereon, and against which the cover B is caused totightly compress when secured upon the can. 'lhe shoulder A is acontinuation of the breast ot' the can.

The horizontal pins b b, rigidly secured to the cylinder ofthe cover,are adapted to tit into recesses e e. These recesses are arched over,and thus, while serving to admit the pins b b, prevent escape of thelacteal i'luid therefrom. The pins b b, in connection with the recesses,not only serve to secure the cover B upon the can, but to compress thebottom ot' the neck or cylinder ot' the cover B against the packing f a,and thereby to render the can perfectly tight against the passage ot'-the milk or atmosphere. For this 'purpose the horizontal arms of therecesses decl-ine a very slight extent from starting-point toterminus,in.order that as the cover is turned the' pins in the socketsmay cause the neck or lower part ot' the cylinder ot' the cover B tocompress the elastic packing with gradually-increasing force, thushermetically tightening the can against escape ofthe iiuid.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

In a milk-can, the combination of the vertical cyiinders E and F andbottom d', having cross-bars hh soldered to the same, and to the in`nerside of the cylinder F, near its base, as and for the purpose set forth.

In testimony that I claim the foregoing as my own l hereto atfixmysignature in presence ot' two witnesses.
